As I gridfinitify myself to organize as much as possible. I wanted a better way to house the tool plates for my Biqu Hermitcrab. The already excellent model by zcohen was printed out and in use but I wanted to be able to have it attached to a gridfinity baseplate.
After a short amount of time, I came up with this model. Even with a very heavy hotend setup such as my biqu h2 v2s revo and M.A.D. Ducting system, it holds it with no problem (though for heavy hotends like this I strongly suggest magnets get installed on the bottom and you use a magnetic base for your gridfinity system.)
This model will fit the standardized gridfinity 6x2mm magnets. I had printed this with a .4mm nozzle and standard .2mm layer settings, though I don't see any reason this can't be printed more coarsely or with a bigger nozzle.
Hopefully this helps your organization like it does mine!
